Abstract

The disclosure relates to a device for cooling components. The device includes a main body and cylindrical and/or conical cooling fins which are formed in the main body and around which a coolant may flow, wherein the cooling fins are formed in parallel first rows and equally spaced apart from one another. Neighboring first rows are arranged offset from one another in the row direction in such a way that the axes of neighboring cooling fins of the neighboring first rows are offset by at least 25% of the hydraulic diameter of the cooling fins. The disclosure also relates to a converter and an aircraft including a device of this type.
